This is one of those subjects, like fuel mix ratios, where discussion never ends. I have used the tank coating POR15 on floats and it seems to hold up. But it’s hard to know how much the weight is increased and how that effects the function of the carb. People report different reports with dope, crazy glue, tank coatings…. I suspect this is related to differences in fuel chemistry. Motor gasoline does not have a defined chemical makeup, and different refineries may send out quite different products as long as they meet basic octane and vapor pressure specs. And around here (Minnesota) fuel with 15% ethanol is becoming common, as the state promotes it as a subsidy to the corn growers and ethanol producers.
